Lecture Notes in Computer Science, 2011
We perform a user study to investigate the psychological consequences of adding interaction techniques to the interface. In a betweensubjects experiment (N = 143), we explore how (i) variations in sheer number of interaction techniques and (ii) addition of a novel technique, i.e., 3D carousel, influence the volume of users' actions, their memory, perceptions of interactivity, as well as their attitudes and behaviors toward a website. Power usage is examined as a potential moderator. First-cut findings from self-reports and log data indicate that the 3D carousel feature has a strong impact on user experience, both positive and negative. It also moderates the curvilinear effect of adding traditional interaction techniques to the interface.
Mobile Interaction with the Real World
Proceedings of the 11th International Conference on Human-Computer Interaction with Mobile Devices and Services - MobileHCI '09, 2009
The Mobile HCI community is moving beyond the interaction between a single user and her mobile device taking the users environment into account. Mobile interaction with the real world concentrates on using mobile devices as tools to interact with real world objects. This workshop continues the successful mobile interaction with the real world workshops 2006 and 2007. Relevant topics include (but are not limited to) mobile interaction with the real world; mobile devices as user interfaces for terminals; and Frameworks, middleware and APIs for the development of applications that take mobile interactions with the real world into account. The workshop combines technical presentations with the presentation of prototypes and focused discussions to drive interaction between participants.
Designing a generalized 3D carousel view
2005
In this paper we describe a 3D carousel view design. We take the basic carousel model and elaborate it to hold an arbitrary number of items in an efficient manner. We equip this model with various interaction methods and a novel component: the termination marker. We also explore more detailed design issues, like animation, by implementing a prototype. We report essential user feedback and how it affected our design.
Interaction Design for Home Information Appliances
This paper describes the design and evaluation of a prototypical information appliance for displaying and exchanging paper and electronic notes and pictures at home. This study addresses two research problems: how to provide minimal and relevant functionality to home users and to investigate novel interaction styles that rely on a combination of computer-vision based technology with commercial pen input devices in order to support easy and learnable interaction. Evaluation of the prototype application suggests that participants were quickly able to use the application and that they liked the idea of combining paper and electronic media.
Red: a framework for prototyping multi-display applications using web technologies
We present the Really Easy Displays framework (RED), a web-based platform to facilitate spontaneous interaction between devices and applications. RED provides a single abstraction for content and interaction between display types, data streams and interaction modalities, and allows developers to create multi-display applications by enabling the sharing of web document object models (DOMs) across displays. We present lessons learned from using RED in our own research, hands-on workshops with developers and interviews with long-term developers over the course of a year. We provide initial evidence that the use of web-technologies in a framework like RED can mitigate some barriers encountered in by multi-display interaction scenarios, and we propose future work to improve RED.

Recently, the diffusion of knowledge on Cultural Heritage (CH) has become an element of primary importance for its valorization. At the same time, the diffusion of surveys based on UAV Unmanned Aerial Vehicles (UAV) technologies and new methods of photogrammetric reconstruction have opened new possibilities for 3D CH representation. Furthermore the recent development of faster and more stable internet connections leads people to increase the use of mobile devices. In the light of all this, the importance of the development of Virtual Reality (VR) environments applied to CH is strategic for the diffusion of knowledge in a smart solution. In particular, the present work shows how, starting from a basic survey and the further photogrammetric reconstruction of a cultural good, is possible to built a 3D CH interactive information system useful for desktop and mobile devices. For this experimentation the Arab-Norman church of the Trinity of Delia (in Castelvetrano-Sicily-Italy) has been adopted as case study. The survey operations have been carried out considering different rapid methods of acquisition (UAV camera, SLR camera and smartphone camera). The web platform to publish the 3D information has been built using HTML5 markup language and WebGL JavaScript libraries (Three.js libraries). This work presents the construction of a 3D navigation system for a web-browsing of a virtual CH environment, with the integration of first person controls and 3D popup links. This contribution adds a further step to enrich the possibilities of open-source technologies applied to the world of CH valorization on web.
TOUCH INTERACTION WITH 3D GEOGRAPHICAL VISUALIZATION ON WEB: SELECTED TECHNOLOGICAL AND USER ISSUES
The use of both 3D visualization and devices with touch displays is increasing. In this paper, we focused on the Web technologies for 3D visualization of spatial data and its interaction via touch screen gestures. At the first stage, we compared the support of touch interaction in selected JavaScript libraries on different hardware (desktop PCs with touch screens, tablets, and smartphones) and software platforms. Afterward, we realized simple empiric test (within-subject design, 6 participants, 2 simple tasks, LCD touch monitor Acer and digital terrain models as stimuli) focusing on the ability of users to solve simple spatial tasks via touch screens. An in-house testing web tool was developed and used based on JavaScript, PHP, and X3DOM languages and Hammer.js libraries. The correctness of answers, speed of users' performances, used gestures, and a simple gesture metric was recorded and analysed. Preliminary results revealed that the pan gesture is most frequently used by test participants and it is also supported by the majority of 3D libraries. Possible gesture metrics and future developments including the interpersonal differences are discussed in the conclusion.
